Title: Improvements in fountain pens
IPC: B43K5/18
Filed: 1950-04-06
Abstract: 722,177. Reservoir pens. PLATEN, B. C. VON. April 6, 1950 [April 8, 1949], No. 8755/50. Class 146 (3). The reservoir of a fountain pen is divided into a secondary space 1a, the volume of which varies with the position of a piston 6 operable from the exterior of the pen, and a primary space 1b of constant volume directly feeding ink to the pen nib 12 and receiving a corresponding quantity of air from the exterior of the pen. -The space 1a is the main reservoir space and communicates with the space 1b through a non-capillary aperture 5 in a removable partition 2, a piece of cloth 3 having a number of capillary holes therethrough and a non-capillary passage 4. The holes in the cloth 3 may have a diameter of about one-thousandth of a millimeter, and the cloth is in the form of a disc between two coarse-meshed nets 7, 8. A common ink and air channel 11 leads from the space 1b to the nib 12. The volume of the passage 4 is at least equal to the largest volumetric expansion likely to occur in the ink in the space 1a due to temperature variations. The cloth 3 acts as an ink barrier, and to cause ink to flow from the space 1a to the space 1b, pressure must be exerted by the piston 6.

Title: Improvements relating to television receiving apparatus
IPC: H04N9/77
Filed: 1956-03-21
Abstract: 826,572. Colour television. GENERAL ELECTRIC CO. March 21, 1956 [March 21, 1955], No. 8850/56. Class 40 (3). Relates to colour television receiving apparatus for signals of the kind comprising a luminance signal Y together with a chrominance sub-carrier modulated at quadrature phase angles by colour difference signals R-Y and B-Y. According to the invention the subcarrier is detected at angles which result in signals other than R-Y and B-Y, and appropriate fractions of the derived chrominance signals are added to the luminance signal so as to produce a modified signal which, when added to the derived chrominance signals, results correctly in the original primary colours R, G and B. In a first arrangement the sub-carrier is detected to derive R-M and G-M, where R G B M = - + - + -, and the fractions - 0.48 3 3 3 (G-M) and - 0.19 (R-M) are added to Y ( =0.59G + 0.30R + 0.11B) to obtain M. This modified signal M, when added to G-M and R-M, then provides G and R. The signal B-M is also obtained from - (G-M) - (R-M) and is added to M to obtain B. Both positive and negative outputs are required from the synchronous detectors and an arrangement employing beam deflection tubes as shown at 101 and 102 in Fig. 4 is employed. Here R-M and G-M are obtained from the appropriate positive output electrodes of the detectors and B-M from a common load coupling the two negative output electrodes. It is necessary for the sub-carrier to be applied at a different level to each detector by means of potentiometer 301, although as an alternative a common input signal may be employed with the detectors arranged to have appropriately different gains. The sub-carrier reference signal is applied to the pairs of deflection electrodes with appropriate phases from across tuned circuits 307, 308 and 312, 313. The fractions of the G-M and R-M signals for addition to the luminance signal Y are obtained from the positive output electrodes via resistance network 316, 317 and applied to the input of the Y channel amplifier 108. The resulting signal M is then added to the R-M, B-M and G-M signals by applying the M signal in common to the three grids of a three-gun cathode-ray tube whilst the other signals are applied to the respective cathodes. Reference is made to arrangements in which the sub-carrier is detected to give R-M and B-M or G-M and B-M. In a second generally similar arrangement, Fig. 5 (not shown), the detection angles are selected to provide signals of the form colour minus L, where L = 0.36R + 0.31G + 0.33B, whilst a third embodiment, Fig. 6 (not shown), is described in terms of a modified luminance signal of the general form L = rR + gG + bB, where r, g and b are any desired normalized coefficients (i.e. r + g + b = 1).

Abstract: 540,063. Toilet soap. LEVER BROS. & UNILEVER, Ltd. (Bodman, J. W.). May 17, 1940, No. 8851. [Class 91] In preparing toilet soap by agitating and working a soap mass in a closed vessel at temperatures of 65-125‹C. and pressures up to 100 lbs. per square inch, releasing the mass to solidify and forming the mass into bars or cakes, the lathering properties are increased by using a soap mass containing 10-15 per cent. of a soda soap produced from oils which are liquid at ordinary temperatures, have iodine values of 78- 145 and are free from glycerides having three or more double bonds, such as soya bean oil, cottonseed oil, corn oil, castor oil or partially hardened whale oil. The moisture content during the working is 8.25 per cent. Air or other gas may be worked with the mass to impart floating properties. The apparatus described in U.S.A. Specifications 1,200,700 and 2,048,286 may be used. Specification 539,718 is referred to.

Filed: 1929-03-21
Abstract: 332,525. Dunlop Rubber Co., Ltd., Chapman, W. H., Pounder, D. W., and Murphy, E. A. March 21, 1929. Latex, treating; spongy rubber. - Aqueous dispersions of rubber &c. which have been rendered capable of gelling on the application of heat, or in the cold after a definite and controllable time interval, are converted into a froth while still remaining reversible, and are subsequently caused to set to an irreversible spongy mass. A froth-forming substance such as soap or saponin is added e.g. to latex, and a froth is made by whipping, or blowing air through the mass. The gelling agent which may be added before or after the froth formation, should be such that it has little or no inhibiting or breaking-down effect on the froth. Suitable substances for use with ammonium oleate are sodium or potassium silico fluoride or ammonium persulphate. When heat is employed for gelling, it should be insufficient to break down the cell structure. Several examples are given, of which the following is typical:-A latex mix as described in Specification 303,545 consisting of 92 parts of rubber, 2.5 parts of sulphur, 0.5 parts of zinc diethyldithio carbamate, 5 parts of mineral oil, 0.3 parts of caustic potash, and 0.5 parts of oleic acid is concentrated as in Specification 290,313. 0.5 parts of ammonium oleate and 1.0 part of sodium silico fluoride are added and the whole is whipped, air being bubbled through if large cells are required. The foam is set cold in moulds or trays, and vulcanized for two hours at 95‹ C, boiled in water for 30 min., and dried. Specification 219,635 also is referred to.

Title: Improvements in or relating to means for starting internal combustion engines
IPC: F01L13/08
Filed: 1925-04-07
Abstract: 252,509. Ricardo, H. R. April 7, 1925. Starting; turning-gear.-In a sleeve-valve engine employing direct fuel injection into the cylinders, in which compression is reduced at starting by varying the timing of the valves, an interlock is provided between the timing mechanism and mechanism for cutting off the supply of liquid fuel, so that fuel injection takes place only when the engine operates at its normal running compression. The timing is preferably so varied that the inlet port remains open during part of the compression stroke, part of the charge being expelled before compression begins. As shown in Fig. 1, reciprocating and oscillating movement is given to each valve by a short crank-shaft C. the shafts C all being driven through skew or worm gearing C<1>, D<1> from a lay shaft D. To vary the timing, the shaft D is moved axially by means of a lever H, a squared portion of the shaft being slidable in a gear-wheel F driven from a gear G on the engine shaft A'. The movement of the shaft H also adjusts simultaneously : (1) a bye-pass or other control K' acting on the fuel pumps L or the supply of liquid fuel to the cylinders; (2) a piston valve J which connects the induction pipe J<2> to a starting carburettor J<4> instead of to the normal air inlet J<1>; (3) a switch controlling the supply of current to a sparking-plug at starting; and (4) a switch controlling an electric starting-motor M. In a modification. Fig. 2, the sleeve valve N is actuated by a lever O connected at one end to a link O<1> and at the other end to an eccentric on a lay shaft P, as described in Specification 234,907, [Class 7 (vi), Internal-combustion engines, Valves &c. for]; the shaft P is driven through skew gearing Q'. Q<2>, P<1>, the gear Q<1> sliding on splines on the engine shaft Q in order to adjust the. timing. The means for varying the valve timing may be combined with that described in Specification 248,909 for reversing the engine, so that a single control will give starting and running valve timings both for forward and reverse running.
